Autumn crocus (Colchicum speciosum)
KOHL-chi-kum spee-see-OH-sum
Synonyms:  Colchicum bornmuelleri of gardens
Genus:  Colchicum
This vigorous cormous perennial has semi-erect, lance-shaped leaves 7 to 10 inches long that emerge in spring, then go dormant in late May. In September, it bears 1 to 3 leafless, goblet-shaped, intense pink flowers with yellow anthers and often white throats.
Noteworthy Characteristics:  Combines well with sweet potato vine, which will cover the gaps left between leaf and bloom times.
Care:  Best in partial sun, since it will fade and burn in full sun. Prefers moisture during their leaf expanding stage.
Propagation:  Separate corms when dormant in summer.
Problems:  Gray mold (Botrytis) and slugs.
